Labeling Machine Roller Accumulates Missing Labels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Labeling machines using pre-pasted labels on a ribbon malfunction when containers are missing on the feeding line, causing the packaging line to stop and leading to inefficiencies.
Innovation Solution
A labeling machine design that includes a rotating carousel and a spongelike or elastic roller to store and accumulate labels that do not find corresponding containers, with a sensor-activated mechanism to position the roller for efficient label collection and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the labeling machine operates at high speed continuously, then productivity is improved, but reliability deteriorates when containers are missing
Solution Approach 1:
The roller is pre-positioned in a retracted state away from the drum, and the sensor system is pre-configured to detect missing containers before they reach the labeling point. When a missing container is detected, the roller is already in position to intercept the label, preventing the label from being wasted or causing a stop.
Solution Approach 2:
The roller acts as an intermediary element between the drum and the container. It intercepts labels that would otherwise be wasted due to missing containers, and the sensor system acts as an intermediary detector that triggers the roller's movement before the label reaches the critical point, enabling continuous operation.
2Reliability
If a sensor system is added to detect missing containers, then reliability is improved, but device complexity increases
Solution Approach 1:
The sensor system is integrated into the existing carousel structure, using the carousel's own rotation and positioning to enable detection. The system uses the natural movement of the carousel to bring containers past the sensor, eliminating the need for separate complex detection mechanisms and allowing the system to detect and respond to missing containers autonomously.

AI summary
A machine for labeling by way of pre-pasted labels printed on a ribbon, comprising a rotating carousel provided with pans for supporting containers to be labeled, and a drum for cutting and transferring each individual label onto the containers which, in the motion of the carousel, progressively face the drum, the machine further comprising a rotating roller, which is adapted to receive from the drum each label designed to be applied to a container that is not present on the corresponding pan of the carousel.
